“The leadership of the business community in identifying, developing and deploying alternatives has been the hallmark of the successful refrigerant transition over the last thirty-five years,” remarked Kevin Fay, executive director of the industry coalition, the Alliance for Responsible Atmospheric Policy. “During this next stage, industry will continue to advance new solutions that are as functional, safe and energy efficient as incumbent technologies, while generating significant economic contributions.”
Numerous experts also noted that new generation air conditioning systems are much more energy efficient than their predecessors, and provide a huge climate benefit from decreased energy use in addition to the benefits from reducing HFCs.
The workshop was a valuable opportunity to raise awareness and confidence of the availability of efficient cooling technologies for a wide range of applications, including residential and light commercial air conditioning, large centralized systems, chillers, and systems suited for special circumstances like those found in mines or data centers.
HFCs are widely used as replacements for ozone-depleting substances (ODS), and air conditioning and refrigeration are the largest users of HFCs. Global demand for air conditioners has grown rapidly due to rising comfort requirements in industrialized countries, increasing industrial production, and growing wealth and demand in emerging economies like China and India. Between now and 2040, a seven-fold increase in global demand for high-GWP HFC air conditioners is expected.
According to a recent study, HFC emissions are increasing rapidly, at a rate of about 10–15 per cent per year. If measures aren't taken, it is estimated that HFCs will amount to 9–19 per cent of total CO2 equivalent emissions by 2050. There is a need now, more than ever, for the expanded use of alternative cooling solutions that will benefit the environment in an economically-viable manner.
The Sustainable Technologies for Stationary Air Conditioning Workshop was organized by the Climate and Clean Air Coalition (CCAC), the governments of Canada, Germany and the USA, and the Alliance for Responsible Atmospheric Policy. There was additional support from the Air Conditioning, Heating, & Refrigeration Institute (AHRI). It took place on the margins of two important industry events in Las Vegas, the 2017 International Air-Conditioning, Heating, Refrigerating Exposition and the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) 2017 Winter Meeting.
The CCAC HFC Initiative supports the development of HFC inventories and studies, information exchange on policy and technical issues, demonstration projects to validate and promote climate-friendly alternatives and technologies, and various capacity-building activities to disseminate information on emerging technologies and practices to transition away from high-GWP HFCs and minimize HFC leakages.
The Climate and Clean Air Coalition is a voluntary global partnership of 50 countries, 16 intergovernmental organizations, and 45 businesses, scientific institutions and civil society committed to catalyzing concrete, substantial action to reduce Short Lived Climate Pollutants (including methane, black carbon and many hydrofluorocarbons). The Coalition has 11 initiatives working to raise awareness, mobilize resources and lead transformative actions in key emitting and cross cutting sectors. SLCP reduction must go hand in hand with deep and persistent cuts to carbon dioxide and other long-lived greenhouse gases if we are to stay under a 2 degrees Celsius warming limit.
